Well there is pretty big inflation on a monthly basis here, so the market cap hasn't fallen as much as the price.

It is also the middle of the month lull, people want to hold Byteball before the airdrop, but that is 2.5 weeks away, so they don't need to worry about it.
Alts generally are down too.

I know everyone says this all the time about every coin, but I actually think that now is a good time to buy here. But to make a short term profit, you probably want to dump before the airdrop, sell when others are buying.
